15/05/2015 JET AVIATION DESIGNS TESTING MACHINE FOR FLUTTER DAMPERS ON CHALLENGERS
Jet Aviation St. Louis has designed and commissioned the manufacture of a testing machine for flutter dampers on Challengers, becoming one of very few facilities in North America capable of testing flutter dampers.
The machine went into service in April, allowing Jet Aviation St. Louis to complete testing of flutter dampers in three to four days and within 24 hours with advance notice. Each Challenger is equipped with six flutter dampers that are designed to help stabilize flight controls in the event of a hydraulic failure.
“This new capability can eliminate up to three weeks of additional downtime for a Challenger while it’s in for other service,” said Chuck Krugh, senior vice president and general manager at Jet Aviation St. Louis. “The dampers previously had to be sent to the original equipment manufacturer (OEM) for testing. Now we can perform those tests on site, providing not only this valuable service but also getting our customers’ aircraft back in the air as quickly and as safely as possible.”
Engineers and technicians at Jet Aviation St. Louis designed the testing machine to the specifications in the OEM’s component maintenance manual and had it manufactured at a facility in St. Louis. The machine performs four tests on the flutter dampers – small, shock absorber-like devices located near the ailerons, elevators, and rudder – and immediately prints out a report on whether the dampers passed or failed each test.
